Active Pass
Active Pass (Saanich: SḴŦAḴ) is a strait separating Galiano Island in the north and Mayne Island in the south in the southern Gulf Islands, British Columbia, Canada. It connects the Trincomali Channel in the west and the Strait of Georgia in the east. The pass stretches 5.5 km from northeast to southwest with two roughly right-angle bends, one at each end. It was named for the USCS Active, a United States Navy survey vessel, the first steamer to navigate the pass in 1855. ) from Galiano Island From 1967 to 2011, the Active Pass light station was part of the British Columbia Shore Station Oceanographic Program, collecting coastal water temperature and salinity measurements for the Department of Fisheries and Oceans everyday for 44 years. Currently, the pass is a major shipping lane and is primarily used by BC Ferries' passenger and vehicle ferry runs between Tsawwassen Ferry Terminal at Tsawwassen, Lower Mainland, the southern Gulf Islands and Swartz Bay Ferry Terminal at Swartz Bay, Vancouver Island. Because the pass has a river's narrowness, the ferries pass extremely close to its shores. It is also used by pleasure craft, fishing boats, freighters and freight ferries, making it very 'active' commercially as well. However, strong eddies and tide rips are always present in the pass, making it a hazardous corridor for smaller vessels to transit.…
